Programming ImageHistogram to display full-scale

tonyc

Hello,

Sometimes when opening up an Image Histogram , it starts up zoomed in on a portion of the histogram range ( with a scroll bar ).
For eg, on a 16bit image, it might start up showing the range 0-16384 only.
Is there a way to force the Image Histogram to open up full range ( showing 0 - 65535 )?
Are there any code examples to show how this can be done?

Also, On the ImageHistogram, you can right mouse click and set up option like "Show/Hide LUT" or "BW Level".
Can this be done via code, to force the ImageHistogram to alway open up a certain way, regardless to whether a user has previously modified settings.

Thanks

Hi tonyc,

The histogram adjusts the range to the camera bit dept used to capture the image. This option is in the context menu (Options/Capture Bit-Depth).

Unfortunately, none of the histogram options have direct commands, but you could adjust them via settings:

    Public Function Histogram_Options() As SimpleScript
        Histogram_Options = New SimpleScript

        With Automate.ScriptingCommands.CodeCommand(Histogram_Options)
            If .Run() Then
                ' User Code Here
                With .Application.Settings("McHistogramChartMini")
                    .Set("m_bHistogram", True)
                    .Set("m_bDynamic", False)
                    .Set("m_bLUT", False)
                    .Set("m_bBWLevels", False)

                    .Set("m_bAxisX", True)
                    .Set("m_bAxisY", False)
                    .Set("m_bAxisLogY", False)
                    .Set("m_bLegend", False)
                    .Set("m_bStatistics", False)

                    .Set("m_bIgnoreROI", False)
                    .Set("m_bActiveFrame", False)
                    .Set("m_bMonoInterpretation", False)
                    .Set("m_bSpatialCalibration", False)
                    .Set("m_bIntensityCalibration", False)
                    .Set("m_bStatisticsRange", False)
                    .Set("m_iExcludeBins", 1)
                    .Set("m_bCaptureBitDepth", False)
                End With
            End If
        End With

    End Function

Thanks,
Nikita.
